Just  short note about using Imagewriters with PC's.  PC firmware
requires the use of DTR and other serial lines fo r effective
communication.  Note that the IW2 cable does *not* have DTR wired.

Remember folks, if you're having problems with a serial device, nine
times out of 10 it's the cable.  You can get cables that support the DTR
handshaking for the IW2.

Also note, if a program accesses the ports directly on the PC, ths
problem may or may not appear.

A good book to read about serial communications is "C Programmers Guide
to Serial Communications" by  Joe Campbell.  It deals directly with the
IBM PC and KAYPRO, but has a lot to say about serial communications and
should be read by those who question authority.
